CALK-lNG-MACHINE.

Specification of Letters Patent.

Patented May 29, 1906.

Application filed September 24:, 1904- Serial No. 225.846,

To all whom it may concern:

Be it known that I, CARL YOUNGSTROM, a citizen of the United States, residing at Meekling, in the county of Clay and State of South Dakota, have invented a new and useful Calking-Machine, of which the following is a specification.

This invention relates to means for recalking horseshoes. So far as I am aware, this has heretofore been a tedious undesirable op eration, and the results thereof are, moreover, unsatisfactory, at least so far as ap-' pearances are concerned.

The object in the present invention is to provide novel means of a simple nature for operating upon a horseshoe, so that the worn calk may be expeditiously and neatly removed and a new one properly placed in position and secured.

The preferred embodiment of the invention is illustrated in the accompanying drawings, wherein- Figure 1 is a perspective view of the machine. Fig. 2 is a vertical longitudinal sectional view therethrough. Fig. 3 is a rear elevation. Fig. 4 is a horizontal sectional view,

and Fig. 5 is a detail perspective view of theclamping-block.

Similar reference-numerals indicate corresponding parts in all the figures of the drawin s.

ln the embodiment illustrated a base or bed 6 is employed having spaced upstanding standards 7, braced by divergently-disposed webs 8, the standards having longitudinallydisposed flanges 9 on their opposing inner faces constituting guides. A tie-bolt 10 connects the standards between their ends and serves as a brace therefor. A plunger is slidably mounted between the standards and frame 12, having guideways 13, that receive the flanges 9. The opposite side portions of said plunger have slots 14, through which the tie-bolt 10 passes.

Located on the base is an anvil or die-block 15,- that is preferably arranged between the webs 8 and has in its upper surface a downwardly-tapering calk-receiving seat 16. The lower end of the plunger carries a head 17, that projects laterally therefrom a sufficient distance to cover the recess 16, said head being movable with the plunger toward and from the recess.

On the opposite side of the standards are ears 18, that are connected with the webs 8 by means of portions 19, said ears and portions forming, with the standards, a seat in which is detachably received a ledger-blade 20, held in place by any suitable means-as, for instance, set-screws 21. It is to be observed that the upper or operative edge of the ledger-blade is curved, as shown in Fig; 1. The plunger is provided in its lower .end with a seat 22, and in the same is fitted a knifeblade 23, having a cutting edge 24, that is made up of angularly-disposed or divergent sections, said blade and edge coacting with the ledger-blade, and the edge thereby effecting a shearing cut, as will be evident.

Holding means for the shoes is employed in the form of a clamping block or head 25 pivoted, as shown at 26, to and between the ears 18, said block having a bill 27, that moves toward and from the ledger-blade and is located sli htly above the plane of the same. Sto fingers 28 project from opposite sides 0 the block contiguous to the bill 27. A lever 29 constitutes the actuating means for the plunger, being pivotally, connected thereto, as shown at 30. A short arm 31 of the lever extends beyond the pivot and is offset, being pivotally connected to the upper ends of links 32, the lower ends of said links embracing and being at 33. The connection 34 between the lever fund the links constitutes the fulcrum for said ever.

It is thought that the manner of operating the machine will be clear by reference to Fi 2. When the actuating-lever 29 is elevate as shown in full lines, the clamping-block will be in its rearmost position and the plunger will be raised. The shoe to be operated upon (designated A) is then placed in a vertical position, with the heel-calks straddling the plunger and with the toe-calk on the upper edge of the ledger-blade. Said ledger-blade constitutes a seat for the shoe, and the curvature thereof conforms substantially to the shape of said shoe. The lever is then swung in the direction of the arrow, whereupon the plunger moves downwardly and the clamping-block swings forward, thus securing the shoe in position. The continued movement of the lever serves to move the cutter downwardly and sever the calk from the shoe by a shear cut, the calk dropping through an opening made in the base or bed for that purpose. The shoe is then in condition to receivea new toe-calk, which is attached in the usual manner, and afterward the shoe is pivoted to the outer portion of the clamping-block, as shown placed in the position shown in dotted lines in Fig. 2, the new calk being arranged in the seat and the plunger having first been elevated. The plunger is thereupon depressed, and the calk will consequently be pressed firmly into position and at the same time properly shaped. With this machine it will be seen that worn calks may be readily removed from shoes and new ones easily and I properly applied, obviatin the tedious hand method. heretofore genera ly employed and presenting a much neater finished appearance. The common actuating means for the plunger and the clamp is an important'feature of the invention, in that the clamp will always properly hold a shoe without regard to its thickness or shape, and yet will permit the plunger to move downwardly, so as to clip the calk from the shoe. I

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will be apparent to those skilled inthe 'artwithout further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is v 1. In a calking-machine, the combination with a base having spaced guide-standards, of a ledger-blade located between the lower portions of the same, a cutter-blade slidably mounted between the standards and movable toward and from the edge of the ledgerblade and along one side of said blade, a clamping device movably mounted on the base and movable toward and from the opposite side of the ledger-blade, and means connected to the cutter-blade and clamp for effecting their said movements toward and from the ledger-blade.

I 2. In a calking-machine, the combination with a reciprocatory cutter-blade, of a pivoted swinging clamp, an actuating-lever having a pivoted fulcrum connection with the l clamp, and a pivoted connection with the reciprocatory cutter.

3. In a machine ofthe character described,

the combination with a movable cutter, of a pivotally-mounted swin ing clamp, a lever pivotally fulcrumedon t e cutter, and a longitudinally-movable link pivoted to the lever and to the swinging clamp.

4. In a calking-machine, the combination with a ledger-blade, of a clamping device pivoted at one side of the same and arranged to hold an article upon the ledger-blade, a re-' ably mounted between the standards and having a cutter-blade at its lower end that coacts with the ledger-blade, a clampingblock pivoted upon the base atone side of the standards and swinging toward and from the ledger-blade transversely of the cutter-blade,

a link pivoted to the clamping-block, and a lever fulcrumed upon the link and having a pivotal connection with the plunger.

6. In a machine of the character described, the combination with a base having an opening therethrough, of upright guide-standards carried by the base at opposite sides of the opening, a ledger-blade arranged between the standards and at one side of the opening,

a reciprocatory cutter mounted in the guides and movable toward and from the opening, a clamp pivoted on the base on the side of the ledger-blade opposite the opening, and common means for reciprocating the cutter and swinging the clamp. In testimonythat I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
